The Worx Nitro WX520L.9 is a 20V cordless circular saw built around a brushless motor that cuts deeper and lasts longer than budget-tier saws. The brushless motor runs 50% longer, delivers 25% more power, and has a 10% longer lifespan than brushed alternatives. It cuts up to 2-9/16 inches deep, which covers most framing and finish lumber you’ll run into on a job site or in the shop. Features include adjustable bevel cuts up to 57°, built-in LED lighting, a one-touch depth adjustment lever, a dust port, and a carry bag. For best performance, pair it with Worx Power Share PRO batteries: the WA3012 (4.0Ah) or WA3571 (5.0Ah), sold separately.
Why Consider This Product?
The Worx Nitro WX520L.9 stands out in a crowded field of cordless circular saws. Here is what makes it worth a serious look.
The brushless motor is the core reason to choose this saw over cheaper alternatives. Brushless motors are more efficient than brushed motors because they have no friction-causing carbon brushes wearing down inside. That translates to 50% more runtime per charge, 25% more cutting power, and a motor that lasts 10% longer before needing attention.
The 2-9/16 inch cutting capacity handles standard framing lumber and most sheet goods without breaking a sweat. That depth puts it in the same range as many corded saws, which is a real advantage when you want to cut freely around the job site without dragging an extension cord.
Features and Benefits
Adjustable Bevel Cuts for Precision
The bevel adjustment knob lets you tilt the blade anywhere from 0° to 57°, giving you full control over angled cuts. Whether you are cutting crown molding angles or framing a roof pitch, you can dial in the exact bevel you need and lock it down securely.
Illumination for Low-Light Environments
The built-in LED shines directly on your cut line so you can see exactly where the blade is going. This is genuinely useful when cutting inside a cabinet box, under a deck, or anywhere the light is bad.
Ergonomic Design for Comfort and Ease of Use
The saw is light enough to use one-handed when needed and the grip is shaped to reduce wrist strain during long cuts. Less fatigue means better control, which matters when you are running through a full sheet of plywood or making repeated cuts on a framing job.
Quick and Effortless Depth Adjustments
The depth adjustment lever moves smoothly and locks firmly, so switching between cut depths takes seconds. You are not hunting for a wrench or fighting a stiff knob mid-project.
Product Quality
The WX520L.9 feels solid in hand without being heavy. The included 24T TCT blade (TCT stands for tungsten carbide tipped, which stays sharp longer than standard steel) produces clean cuts right out of the box. The brushless motor design also means fewer internal parts that wear out, so the saw holds up well under regular use.
What It’s Used For
This saw covers a wide range of cutting tasks. Here is where it earns its keep.
Precision Cutting
The bevel range and sharp TCT blade make this saw reliable for finish work where accuracy matters. You can cut tight miters for trim, rip sheet goods for cabinetry, or crosscut framing lumber cleanly.
Versatile Lumber Types
The 2-9/16 inch depth handles pine, fir, plywood, and most hardwoods without bogging down. The brushless motor holds its speed better through dense material than a brushed motor would at the same voltage.
Work Area Illumination
The LED lights the cut line so you follow your mark accurately without needing a separate work light pointed at the blade. This keeps your cut line visible and your hands where they belong on the saw.
Easy Depth Adjustments
Setting the blade just proud of the material thickness reduces blade exposure and makes cuts safer and cleaner. The lever-based depth adjustment on this saw makes that quick to do between cuts rather than something you skip because it is too fiddly.

FAQ’s
-
Can I use this circular saw without the batteries recommended by Worx Nitro?
- Yes, other 20V Power Share batteries will work, but for the best runtime and power output, use the Power Share PRO batteries: WA3012 (4.0Ah) or WA3571 (5.0Ah).
-
Does the circular saw come with a carry bag?
- Yes, the Worx Nitro WX520L.9 includes a carry bag so you can store and transport it easily.
-
Can the bevel angle be adjusted to specific angles other than 57°?
- No, the bevel knob lets you tilt the blade anywhere up to 57°, but it does not lock into preset angles between 0° and 57°.
What Customers Are Saying
Buyers consistently highlight the brushless motor’s power and the accuracy they get from the adjustable bevel and LED work light. The lightweight body and comfortable grip come up often too, with users noting they can cut for long stretches without fatigue. The main complaint across reviews is that the battery and charger are sold separately, so factor that into your budget.
Overall Value
The WX520L.9 is priced competitively for a brushless cordless circular saw with a 7.25″ blade. You get solid cutting capacity, a beveling range up to 57°, and an LED light that genuinely helps on darker job sites. Just keep in mind the battery and charger are not included, so if you are not already in the Worx Power Share ecosystem, add that cost to your comparison.
Tips and Tricks for Best Results
Get the most out of your WX520L.9 with these practical tips:
- Always wear safety glasses and gloves before you start cutting.
- For the best runtime and motor performance, pair the saw with Worx Nitro Power Share PRO Batteries: WA3012 (4.0Ah) or WA3571 (5.0Ah).
- Connect a vacuum to the built-in dust port to keep your cut line visible and your workspace clear.
- Switch on the LED light whenever you are working in a dim garage or shaded outdoor area.
- Follow the manual for blade changes and routine maintenance to keep the saw cutting safely and accurately over time.
Final Thoughts
The Worx Nitro WX520L.9 is a capable 7.25″ cordless circular saw that handles framing cuts, sheet goods, and bevel work without breaking a sweat. The brushless motor delivers real power, the bevel range is generous at 57°, and the LED light is a practical touch rather than a gimmick. Battery and charger are sold separately, so it suits you best if you already own Worx 20V batteries. If you do, this saw is a smart addition to your shop.
